Feruer or Ferouer (Persian) [from fravashi or farvarshi] A highly mystical term in ancient Persian theology, signifying generally a spiritual veil, lining, or vehicle of a still more spiritual and higher original. Consequently in mystical thought, the feruer or fravashi need not necessarily always be of the higher spiritual type or class; if the original divinity is not high, its feruer, lining or darker side, will also not be of a high spiritual character.
